Figure 1: — (A) Schematic of the LSR device. (B) Laser speckle pattern reflected from blood at a single time point. (C) Schematic of LSR algorithm used to measure blood viscoelasticity.²⁶ First, the intensity autocorrelation curve is measured from time-varying speckle patterns from which the mean square displacement (MSD) of light scattering blood cells (represented by white circles) is measured. In the final step, the viscoelastic modulus G* is measured from the MSD.
